Universal Rite

Casting Time: 20 minutes
Range: 30 feet
Components: V, S, M (a shard of cold iron, pressed into the ground)
Duration: Until expended

You brand an undead creature with a curse of divine retribution. The target becomes vulnerable to radiant damage and takes an additional 1d6 psychic damage whenever it suffers radiant harm. If the branded creature attempts to flee beyond 60 feet of you, it must succeed on a Charisma saving throw or be compelled to return. The brand remains until the creature is destroyed, the shard is shattered, or you willingly release it.
